Hi All,

I am experimenting with the Google App Engine and have a question.

For the sake of simplicity, let's say my app is modeling a computer network (a fairly large corporate network with 10,000 nodes). I am trying to model my Node class as follows:

class Node(db.Model): name = db.StringProperty() neighbors = db.SelfReferenceProperty()

Let's suppose, for a minute, that I cannot use a ListProperty(). Based on my experiments to date, I can assign only a single entity to 'neighbors' - and I cannot use the "virtual" collection (node_set) to access the list of Node neighbors.

So... my questions are:

1. Does SelfReferenceProperty limit you to a single entity that you can reference?
2. If I instead use a ListProperty, I believe I am limited to 5,000 keys, which I need to exceed.

Thoughts?

Thanks, John
